Energy needs oxygen. Oxygen needs iron.
Iron
Iron is a fundamental mineral in dog nutrition, responsible for transporting oxygen through the blood and fuelling energy production in every cell. Without iron, the body cannot deliver oxygen efficiently – leading to fatigue, weakness, and poor performance.
Iron is a key component of haemoglobin and myoglobin, the molecules that carry oxygen in the blood and muscles. It also supports brain development, immune defence, and enzyme activity. Balanced iron intake is essential – too little leads to anaemia, too much can cause toxicity.
Iron is the lifeblood of vitality – fuelling movement, focus, and resilience.
Core functions of iron include:
- Carrying oxygen via haemoglobin in red blood cells
- Supporting muscle energy through myoglobin
- Maintaining strong immune function
- Helping enzymes in metabolism and detoxification
- Supporting growth, stamina, and cognitive health
Iron keeps every heartbeat strong and every step energised.
Too little drains life – too much overwhelms it.
